Q2. What is the role of extension services in determining the implementation of adaptation strategies?
Extension services are, for instance, very important in determining the implementation of adaptation strategies, which could result in more food security for all farmers irrespective of their unobservable characteristics.
Q3. What is the effect of the selection model on the net revenue functions?
if the error terms of the selection model (1) ηij are correlated with the error terms uij of the net revenue functions [3a]– [3m], the expected values of uij conditional on the sample selection are nonzero, and the OLS estimates will be inconsistent.
Q4. What are the strengths of the thin plate spline method?
Its strengths are that it is readily available, relatively easy to apply, and accounts for spatially varying elevation relationships.
Q5. How do the authors establish the admissibility of these instruments?
The authors establish the admissibility of these instruments by performing a simple falsification test: if a variable is a valid selection instrument, it will affect the decision of choosing an adaptation strategy, but it will not affect the net revenue per hectare among farm households that did not adapt (Di Falco, Veronesi, and Yesuf 2011).
Q6. What is the role of extension services on the probability of adopting the strategies?
Government extension services are positively correlated with the probability of adaptation via changing crops in isolation and in conjunction with soil conservation measures, while farmer-to-farmer extension increases the likelihood of adopting strategies only in combination.
Q7. What is the significance of the standard error in the selection instrument?
In addition, standard errors are bootstrapped to account for the heteroskedasticity arising from the two-stage estimation procedure.
